Woody plants that are native to, or
naturalized in, Oregon are listed below in alphabetical order by their
"scientific names" (their Latin binomials), more or less according to their height, ranging from large trees
to low growing ground covers. Naturalized plants refer to those
plants that are not indigenous to Oregon but were introduced into the State and have become widely established
in natural areas. Many such plants are considered invasive, since they
frequently damage natural areas by altering ecosystem processes, in part, through the displacement of, or
hybridization with, native plants.

Note: recent evidence indicates that the apparent Abies concolor found in Oregon forests are actually a hybrid between Abies concolor and Abies grandis, Grand Fir, and are now designated as Abies concolor × grandis.
